Lightroom: Support for all media - a true Digital Asset Management Application

I would like Lightroom to support all types of media for the purpose of organizing and viewing thumbnails where appropriate. This would include some currently unsupported photo files (such png), as well currently unsupported video files (such as .mts), audio files, pdf files, and anything else that I care to include in the catalogue.

This would make LR indispensible for me when I do projects that combine photography with other disciplines, such as video and animation, as well every day use.
